  1. Acceptor

    In semiconductor physics, an acceptor is a dopant atom that when added to a semiconductor can form a p-type region. For example, when silicon, having four valence electrons, needs to be doped as a p-type semiconductor, elements from group III like boron or aluminium, having three valence electrons, can be used. The latter elements are also called trivalent impurities. Other trivalent dopants include indium and gallium. When substituting a Si atom in the crystal lattice, the three valence electrons of boron form covalent bonds with three of the Si neighbours but the bond with the fourth neighbour remains unsatisfied. The unsatisfied bond attracts electrons from the neighbouring bonds. At room temperature, an electron from the neighbouring bond will jump to repair the unsatisfied bond thus leaving a hole. The hole will again attract an electron from the neighbouring bond to repair this unsatisfied bond. This chain-like process results in the hole moving around the crystal and able to carry a current thus acting as a charge carrier. The initially electroneutral acceptor becomes negatively charged.
